Apple has released an update to address vulnerabilities and extend LTE wireless broadband on its iOS mobile operating system.
Apple said that the iOS 6.1 update would allow an additional 36 carriers to offer LTE service to iPhone and iPad users. The update will also expand language support for the Siri personal assistant tool.
"IOS 6 is the world's most advanced mobile operating system, and with nearly 300 million iPhone, iPad and iPod touch devices on iOS 6 in just five months, it may be the most popular new version of an OS in history," said Apple senior vice president of marketing Philip Schiller.
"IOS 6.1 brings LTE support to more markets around the world, so even more users can enjoy ultrafast Safari browsing, FaceTime video calls, iCloud services, and iTunes and App Store downloads."
In addition to expanding LTE support, iOS 6.1 will bring a number of stability and security fixes. Among the fixes are patches for elevation of privilege flaws, cross-site scripting vulnerabilities and an authentication bypass flaw.
In addition to iPad and iPhone, the company is posting the update for iPod Touch fourth generation and later.
The update is the first major release for iOS since the 6.0 update was posted last September. The release was widely panned by reviewers for the shoddy quality of its Maps application, which Apple had opted to include over Google Maps for iOS.
